Using RDF Linked DataTo Solve

Real Problems


Situation Analysis

Agility is the timeless pursuit of enterprises and individuals alike. In all cases, access, integration,

and dissemination of data is pivotal.


What is Linked Data?

A term coined by Tim Berners-Lee that describes HTTP-based Data Access by Reference for the Web

An unobtrusive tweak to the Web that accentuates its core architecture Use of HTTP based Identifiers for Naming

“Things” Implicit association of Identifiers with their

metadata.


Problems

Identity - People

- Places

- Ideas

- Other Things

Data Access & Integration


Problem - Identity

Who Am I ?

What are my credentials ?

Why do I repeat the above, each time I encounter a new:

Each Web Application / Service

Each Enterprise Application / Service.


Solution – Identity Problem

Get Yourself a Data Space that delivers:

A personal HTTP based ID (a URI)

Bind Your ID to an X.509 Certificate

Bind Certificate to your HTTP User Agents (e.g., Browser)

Bind Certificate to your Profile (e.g., a FOAF space).


Solution – Identity Problem Contd.

With the your HTTP ID in place you can then achieve the following:

Visit places on HTTP networks with no login and credentials repetitions (Intranet or Web)

Use ACL based policies to confine data access to specific groups of people.


Collective Intelligence


Problem: Data Access & Integration

Enterprise Silos generated by applications bound to: Disparate DBMS Engines & Data Models Disparate Development Frameworks

Data Silos on the Web such as: Social Networking Services Discussion Forums Blogs Wikis etc.


Solution – Data Access & Integration

Use Middleware to generate Conceptual Views over Heterogeneous Data Sources using:

RDBMS to RDF mapping technology e.g., RDF Views over RDBMS data sources

RDFizers to convert unstructured and semi-structured data to RDF.
